Found the answer!

If you have Jetpack installed, go to the Jetpack Settings, Appearance and turn off “Mobile Theme”. I’ve tested it on the browsers that were affected and it works.

I have the same problem. It works with mobile…. sometimes. Other times it loads an ugly layout that’s not remotely close to what it’s supposed to look like. It also does this on desktop browsers including Firefox, MS Edge, IE and Chrome. Clearing the page cache for ALL the pages sometimes fixes it. But the problem returns even when there have been no changes to the layout.
